Lexus engineers have a way of testing to see
if their cars are air-tight.

They would put a cat in the car and close it
up. They would check the car again in 24
hours. If the cat was dead, it passed the test.

Chrysler heard about this and decided to try it.
They put a cat in one of their cars and closed
it up. When they checked it again in 24 hours,
the cat was gone.
